Serving a large file through PHP without hitting memory_limit

Ran into a little problem hitting the memory limit for PHP when serving 100MB+ files through a script like:
$file = @fopen($filename,"r");<br/><br />
if ($file)<br />
{<br />
while(!feof($file))<br />
{<br />
print(fread($file, 1024*4));<br />
flush();<br />
ob_flush();<br />
}<br />
@fclose($file);<br />
}
Found that you need to call ob_flush() as well as flush() since flush() has no effect on the buffering scheme of your web server.
Just thought I’d throw that out there for anyone else.
